2 Claims. (Cl. 114-208) This invention relates to boat anchors and hasfor its object an anchor which comprises a plurality of lever arms,usually a pair, formed with flukes at their front ends, the lever armsbeing pivoted between their ends, a shank to which the lever arms arepivoted and to which the anchor line is secured, and a float or buoyantmember rigid with the lever arms in the rear of the pivot and usuallyalso a weight rigid with the lever arms in the rear of the pivot, thecombined weight of the rear portion of the lever arms, the float, andthe weight, acting to slightly overbalance the flukes and the frontportion of the lever arms and fold them about the pivot up alongside theshank when the anchor is lifted out of the water. When the anchor isdropped into the water, the float lifts the rear ends of the lever armsupwardly about the pivot, causing the flukes to incline downward to diginto the bottom of the body of water.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure 1 is a view illustrating the anchor attached by the anchor lineto the bow of a boat.

Figure 2 is a plan view of the anchor.

Figure 3 is a side elevation thereof, the position of the anchor when inthe water being indicated in broken lines.

Figure 4 is a fragmentary view of the upper end of the shank of theanchor showing the shank embracing the pulley on the boat, over whichthe anchor rope runs when the anchor is pulled up.

The numeral 1 designates the body of the anchor consisting of a pair offluke carrying arms 2 pivoted at 3 between their ends to the shank 4 towhich the anchor line 5 from the boat B is secured. 6 are the flukes atthe front ends of the lever arms 2. The shank 4 is also double orbifurcated, and the pivot 3 is a pin or shaft extending through twoalined bearing openings in the bifurcations of the, body 1, and of theshank 4.

7 designates a float or buoyant body rigid with the lever arms on theopposite side of the pivot 3 to that on which the flukes 6 arelocatedthat is, on the rear of the lever arms.

8 is a counterweight rigid with the lever arms 2 in the rear of thepivot 3. The combined weight of the float and the lever atrms 2 in therear of the pivot 3 and the counterweight 8 is suflicient to slightlyoverbalance the fluke carrying arms and fold them upward alongside theshank, when the anchor is lifted out of the water. When the anchorenters the water, the rear end of the body 1 and the weight 8 is buoyedup by the float 7 and the flukes shifted to point downward at aninclined angle, as shown in dotted lines, Figure 3, and hook into thebottom of the body of water. The pivotal movement downward of the flukecarrying arms 2 is limited by the weight coming in contact with theshank 4 at 9.

The bifurcations of the shank 4 are spaced apart and secured together bya pair of tie bolts 10 with spacers thereon to which the anchor rope orline is secured.

2,696,186 Patented Dec. 7, 1954 The tie bolts 10 are located asufiicient distance below the upper end of the shank 4 to provideupstanding ears or a recess 11 to embrace the pulley of the anchor ropeguide on the boat when the anchor is fully pulled up. The location ofthe tie bolts provide ample space for the knot of the rope tied to thetie rods between the ears 11 and also for the ears to embrace orstraddle the side of the rope guide or pulley 12.

By the shank and rope arrangement, the anchor is firmly held to the boatby the anchor or tie rope when the anchor is fully out of the water, andalso the anchor can be lowered into the water by means of the tie oranchor rope without the operator leaving his position or seat in theboat.

Owing to the pivotal arrangement of the fluke carrying arms and theshank 4 and to the location of the float and the counterweight relativeto the pivot, the anchor is easily handled or placed into and removedfrom the water. When being removed, the flukes fold up into verticalposition alongside the shank and when being dropped into the water, thefloat elevates the rear ends of the fluke carrying levers, causing theflukes to point downward at an oblique angle in position to dig into thebottom of the body of water.

What I claim is:

l. A boat anchor comprising a shank having a pivot pin at one end andbeing provided with means located intermediate its ends for theattachment of the anchor rope, a pair of arms mounted on said pivot pinintermediate their ends, like end portions of said arms divergingoutwardly from said shank and flukes mounted on said ends of the arms, afloat rigidly mounted on the opposite ends of the arms, said armsassuming a vertical position parallel with the shank with the divergingfluke ends of the arms extending upwardly when the anchor is out of thewater, said float being operable when the anchor is submerged to tiltthe arms about said pivot pin and move the fluke ends of the armsdownwardly into an oblique angle with the shank. and stop means limitingpivotal flmovement of the arms under the buoyant action of the oat.

2. A boat anchor comprising a shank having spaced apart side walls andtie bolts between the side walls and located intermediate the upper andlower ends of the shank and providing means for the attachment of theanchor rope, a pivot pin mounted in the lower ends of said side walls,the side walls providing a space for the knot of the anchor rope andextending upwardly from said tie bolts to form spaced ears at the upperend of the shank to embrace the sides of the guide on the boat for theanchor rope when the anchor is pulled up against the boat, a pair ofarms mounted on said pivot pin intermediate their ends, flukes mountedon like ends of the arms and a float rigidly mounted on the oppositeends of the arms, said arms assuming a vertical position parallel to theshank with the fluke ends of the arms extending upwardly injuxtaposition to said ears when the anchor is out of the water, saidfloat being operable when the anchor is submerged to tilt the arms aboutsaid pivot pin and move the fluke ends of the arms downward into anoblique angle with the shank, and stop means for limiting the pivotalmovement of the arms under the buoyant action of the float.
